my o2 mini no display ( lcd ok ) only light. any one have service manual? plz help me
You mean the LCD works, but theres no light? Well as always, start out with the basics - try holding down the Power button while the LCD is on. The Power button can also be used to toggle the backlight on and off, you see .

OK so the backlight is on, but your screen shows just a blank white... try putting it into bootloader mode by holding the Power + Camera + Soft Reset buttons. If the display just blanks out (no backlight and absolutely nothing on the LCD) then its likely that your LCD is dead, or that its connection inside the phone is loose or damaged (which is unlikely, but I wont rule that out yet).
If it does manage to get into bootloader mode (displaying 'Serial' and 'v1.xx') then you're in luck - its a ROM problem. Try flashing it with another ROM in case the one you have is corrupted.
Every now and then I go to use my SPV M5000 and the device is dead, no response to pressing the power button or even holding it (in case the screen had switched off). Pressing the reset button with the stylus usually works, if not holding it in for a short delay usually works in getting it back together.
This happens on any power source, Mains, Battery, plugged into USB. On scanning through this group I've bought a replacement battery but that has had no effect.
Was tempted to try and find a cracked screen HTC Universal on sale @ eBay and transplant stuff across but thought I'd better check on here first.
So, any ideas anyone?
Hey all, I'm new to the forums but I can't wait to get my 8125 working. I bought a replacement screen on ebay and a broken 8125.. on receipt all I got was a white screen, then last night I replaced with the new screen and got the cingular logo and the windows mobile "touch anywhere to set up.." message.
Well, touching it did nothing, and the keyboard didn't work, so i opened it up again.
Somehow when I opened it up, the power switch button circuit thing detached from the mainboard (and it looks like the owner before me had actually crazy glued it on!!) .. and now the thing won't power up, won't show a charge light... nothing at all when plugged in or attached to my PC. So I hope that detached power button is the culprit. Upon further inspection I saw that yet another had detached but I can't seem to find where it landed... this one for the little button next to the slider, I don't really know what it does yet.. .
.. so I guess first step is to solder that power button back on and see what happens. Does it sound like a missing power button circuit thing would cause the unit to no longer power on at all (even when soft reset when connected to PC, which used to power it on?)

i did this. it is hell to solder on. I would say replace the phone

Argh.. well, i'll give it a go with the power switch.... do you think it will affect the phone to be missing the comm manager switch off the mainboard too... or will the phone still function without this piece soldered on?

Yes, the power on/off button being broken is the reason why you had a white screen, and only getting the splash screen after replacing the touch screen. If you're a good assembly man, I'd suggest try to solder the button back ln place or replace the device. As for the button by the volume slider, that's the comm manager button. If you can ever get to the homescreen, the comm manager icon to activate the comm manager (bluetooth, WiFi, etc. is in the system tray at the bottom of the homescreen.
It sounds to me the new screen was replaced improperly, accounting for nothing happening when you tap it.Try re-installing the replacement screen.

I have problem with power button. when push pwr button dont,t off pda, but when hold pwr then lights off.
Power is never shut off in PDAs, thats the way PDAs have been designed.
I have the same problem, he is not talking about a full power down. If you hit the power button quickly the phone does nothing. However if you hold the power button down for about 2-3 seconds the lcd light turns off as it should.
Because of this I have to wait 1 minute for the unit to suspend before putting it back in the holster.
Does anybody have any idea as to why this might be happening. Im not new at this so hard reset, soft reset.. new rom... new radio...turning up side down while chanting. It does not change......
It will do it right one or twice in a week.
Maybe somebody that understands the signal that the unit receives upon pressing the power button might be able to shed some light on this.... Again the button does seem to operate just not suspend when pressed normally (1 second or less)
I have done some more research and this seems to be a common problem for some with BAs but nobody has found out why. There must be some kind of common hardware fault.. Does the power button send only one signal or is it a multi signal device.

Do you have a problem with turning on? First, we need to know whether it is hardware issue or not...
What you can do in the mean time with the turning off problem is by installing a poweroff app like shutdownme, psshutxp, etc etc...
Absolutely no problem with turning on from standby... Right now i just lock the phone before placing it back in the holster.
To make it clearer if you HOLD the power button down the backlight will turn off only. It will still show the display image and keys will still function (it dims)
Well, I had the same issue with the latest WM5 ROM. I thought I was too stupid to press the button, then I thought the button was broke, then I thought, I'll have to live with it.
Now that I have flashed to WM6, no problems at all! Never even came to my mind that this problem once existed. So I guess that some ROMs just have this particular bug?
Stefan
I have tried all the roms as well as 2003 and have the same issue in all of them. And im not alone.
Power off Problem
I'm in same condition.
Had the same problem when using WM2003 second Ed.
Now I've installed WM6 but nothing changed:
I cannot power-off/suspend but can turn off backlight if press and hold power button.
When in standby the button works fine to turn on the device.
Also, sometimes volume turns up continously with "noisy" beep ...
Anybody solved this problems?
Thanks,

Power button has two modes:
1. Click mode: Click it once for a short duration. This turns off backlight and can be resumed by pressing it again or by pressing OK button
2. Press and Hold mode: Press and hold for few seconds and release. This mode will dim the backlight and no other button will bring it back. This is some kind of deep sleep in battery mode. To resume the original setting, press and hold Power button again for few more seconds.
(p.s.: I am not sure if this behavior is true for all the BA models)
April 1,
I know these modes...
It seems that "mode 1" doesn't work at all...
I would activate "Button Lock" (settings-->button--> Lock(tab)--> "lock all buttons except power button") to turn-off backlight and "lock all buttons except power button" but I cannnot...
You solved this problem?
I have had this issue of not being able to power off. One way I always got out of it was by clearing the registry hive. Unfortunately this brings the PDA back to the basic ROM. At this point the power button worked without any issues. Upon reloading the software the problem may come back. I believe the issue is related to some programs. I can't recall which program it was that seemed to cause the issue. One other thing I think that also worked was just entering the registry and getting back out and doing a hard reset.
I had the same problem with my 6600. the message button also didn't work. Believe it or not, to fix it. I banged the lower half (4-way area) on my desk a few times. Not hard enough to break the screen. But prolly hard enough to free what was prolly a sticky key. And now everything is working.
i am too
the same ...
when i press the power quickly , nothing happen
when i press the power for 2 sec. the backlight turns off
i tried every thing .... including formatting my BA
any one solve it ???
I have this same problem, my power button does`t work. i tried installing different roms but without any chance to fix it. maybe its an mechanic issue. i will change pwr button, i hope this work.
Look at one of my previous posts. I fixed it, twice, and other users have used the same metod to fix it. I think the problem is "hung bit" hardware related because you can also send it in for service, and they will change a chip, but i never had to.
Hello to all,

PLEASE, anyone know how fix it?
